Clinical Effectiveness Of Minimally Invasive Posterior Sacroiliac Joint Fusion In Treating Sacroiliac Joint Pain

Purpose: To discuss the safety and effectiveness of minimally invasive posterior sacroiliac joint fusion in treating sacroiliac joint pain via a retrospective outcomes study of 10 minimally invasive posterior sacroiliac joint fusion patient.Materials method: Ten consecutive patients with a mean age of 67-years-old(rage 53-86 years). Enrolled subjects included two males and eight females. The mean follow-up time for CT to assess fusion was 13 months(range: 12-15 months). The visual analog scale(VAS) for pain, Oswestry Disability Index(ODI) for back function were collected pre-operationly and post-operationly to assess clinical outcomes.During follow-up,patients were assessed radiologically for radiographic bony union and asked to rate theirsatisfaction with the procedure.Results: Out of the 10 patients 10 SI joints were considered symptomatic and operated, and 10/10 joints successfully fused radiographically(a 100% fusion success rate). There were no intraoperative complications.All patient-reported outcomes showed both clinically and statistically significant improvement at 13 months(p < 0.001 for each of the following): VAS improved by 3.9 points, ODI scores improved by.39.5 points. The average procedure satisfaction rating(PSR) was 7.7 out of a maximum 10(range 1-10). Average estimated blood loss was less than 50 mL, and average length of stay was three day.Average operation time was 40 minites.Conclusions: Minimally invasive posterior sacroiliac joint fusion is a safe and effective procedure for patients with SI joint disorders who have failed conservative care.
